Modification in Geometric Structure of Double-Sided Axial Flux Switched Reluctance Motor for Mitigating Torque Ripple

Abstract

Due to very high torque/weight ratio, the axial flux switched reluctance motor (AFSRM) can be appropriately used in many applications, especially electric vehicles and aerospace systems. Since the torque ripple is generally the drawback of SRMs, a new structure is suggested for the double-sided AFSRM in which the torque ripple is significantly reduced. In order to show the effectiveness of the technique proposed for reducing the torque ripple, the 3-D finite-element (FE) transient analysis of a typical 8/6 double-sided AFSRM is carried out using MAXWELL FE package and the simulation results are presented.
